1. Divide the first row by -4
(1, -5/4, -3/2)
2. Multiply the first row by -2
(-2, 5/2, 3)
3. Subtract the first row from the third row and restore it.
1 (1, -5/4, -3/2)
3 (0, -15/2, 1)
4. Restore the first row to the original view
(-4, 5, 6)
5. Divide the second row by 4
(0, 1, 1)
6. Multiply the second row by -15/2
(0, -15/2, -15/2)
7. Subtract the second row from the third row and restore it
2 (0, 1, 1)
3 (0, 0, 17/2)
8. Restore the second row to the original view
(0, 4, 4)
9. Multiply the main diagonal elements
-4 x 4 x 17/2 = 136

AAAAAAAAAAAAAAARRRRRRRGGGGHHHHH
Answer:
95
Step-by-step explanation:
Week Number of Beetles
0 16
1 16 + (16/4) = 20
2 20 + (20/4 ) = 20 + 5 = 25
3 25 + (25/4 ) = 25 + 6.25 ≈ 31
4 31 + (31/4) = 31 + 7.75 ≈ 31+8 ≈ 39
5 39 + (39/4) = 39 + 9.75 ≈ 39 + 10 ≈ 49
6 49 + (49/4) = 49+ 12.25 ≈ 49+12 ≈ 61
7 61 + (61/4) = 61 + 15.25 ≈ 61 + 15 ≈ 76
8 76 + (76/4) = 76 + 19 = 95
Hence there will be approximately 95 beetles by 8th week
